Working Principles

The ICL3222CPZ operates based on the RS-232 standard, which defines the electrical characteristics of serial communication between devices. It uses a combination of voltage levels and timing to transmit and receive data. The IC incorporates line drivers and receivers to convert the logic-level signals from the connected devices into RS-232 compliant signals.

When transmitting data, the IC converts the logic-level signals into RS-232 voltage levels and sends them through the appropriate output pins. On the receiving end, the IC receives RS-232 signals and converts them back into logic-level signals for the connected device to interpret.
